Abstract

Salah satu alternatif sumber energi listrik terbarukan adalah PLTS (Pembangkit Listrik Tenaga Surya). Kinerja PLTS sendiri sangat dipengaruhi oleh parameter-parameter lingkungan dari photovoltaic array diantaranya adalah, suhu permukaan photovoltaic array, suhu lingkungan, dan solar irradiance. Penelitian ini menggunakan rancang bangun sensor solar irradiance berbasis sel photovoltaic sebagai pengganti pyranometer, sensor DS18B20 sebagai sensor suhu permukaan dan DHT11 sebagai sensor suhu lingkungan. Dari hasil data yang didapat effisiensi tertinggi yaitu 14,1% didapat saat solar irradiance sebesar 374,337 W/m2, suhu lingkungan sebesar 31oC dan suhu permukaan sebesar 33,35oC. Efisiensi terendah sebesar 6,45% didapat saat solar irradiance sebesar 454,593 W/m2 , suhu lingkungan sebesar 32oC dan suhu permukaan sebesar 42,8oC. Efisiensi dari photovoltaic array ini sangat dipengaruhi oleh suhu permukaan dan suhu lingkungan, semakin tinggi suhu permukaan dan lingkungan maka semakin rendah effisiensi dari photovoltaic array. Sedangkan solar irradiance mempunyai pengaruh yang tidak langsung, karena saat nilai solar irradiance naik, maka suhu permukaan dan suhu lingkungan juga naik. ======================================================================================================= One alternative source of renewable electrical energy is solar power plant. Solar power plant performance is greatly influenced by environmental parameters including the photovoltaic array surface temperature, ambient temperature, and solar irradiance. This study uses solar irradiance sensor based on photovoltaic cells as a replacement of pyranometer, sensor DS18B20 as a surface temperature sensor and DHT11 as the ambient temperature sensor. The results of obtained data, the highest efficiency is 14.2% acquired at 374,337 W/m2 for solar irradiance, 31oC for ambient temperature and 33,35oC for surface temperature. The lowest efficiency is 6.45% acquired in solar irradiance at 454.593 W / m2, ambient temperature at 32oC, and the surface temperature at 42,8oC. Efficiency of photovoltaic array is highly influenced by its surface temperature and ambient temperature, the increasing of surface temperature and ambient temperature make the efficiency of photovoltaic array decreased. Whereas solar irradiance had indirect effects, because when solar irradiance is increasing then the surface temperature and ambient temperature increase.
